JR Xs3 Not for Boat use!! no warranty!!!
A Tampon in the radio box and a Condom to wrap the reciever in! Try to explain that to your wife! I started using baby bottle liners to wrap my recievers in, a cheap way to do it. I cut them off at the 6 oz. line.
I don't know about the JR reciever, but I have one in a CEN Racing Grey Thunder that got wet and sat in my basement for about 2 weeks before I tried some Aeroplate on it. It was dead before I sprayed some in it and it brought the reciver back to life!
